Nickel bis{4,6-dibenzhydryl-2-[(arylimino)methyl]phenoxylate} complexes: Synthesis, structures, and catalytic behaviour towards ethylene and norbornene†
Abstract
A series of 4,6-dibenzhydryl-2-[(arylimino)methyl]phenol derivatives (L1–L6) and their nickel complexes (Ni1–Ni6) were synthesized and characterized by spectroscopic and elemental analyses. Molecular structures of Ni3 and Ni6 were further confirmed by single-crystal X-ray crystallographic studies. When activated with ethylaluminium sesquichloride (EASC), all nickel pre-
